WebAug 13, 2024 · A fixed-point number is represented with a fixed number of digits before and after the radix point. In FPGA, a fixed-point number is stored as an integer that is scaled by a specific implicit factor. For example, the common notation fix16_10 used by Xilinx stands for a 16-bit integer scaled by 2 10. north korean whisky
